Rlly - i dont know whats so hard on posting logfiles....So please - post ur log files. What else but guesses could not be set up otherwise. Does the domain have a A Record? Did u done changes in the last 24hrs to this A Record? Does it points to the right Server? (https://dnschecker.org/) Did u can activate "SSL" for it? Did u can activate "Lets Encrypt" for it? Did u selected the http to https rewrite? Set ur server in loglevel debug and post logs after trying reactivate ssl.
